Innovative Engineering Solutions to reduce the stress on Natural Water Resources Brook Hill Chief Environmental Engineer Minerals & Metals WorleyParsons Services Pty Ltd
Why we have to act (Green) Population: 6 billion rising to 10 billion by 2050 Forest: over 50% of all forest cover lost Between 1 – 1.5 billion people without access to clean water Ocean Health: claims that 75% fish stocks destroyed worldwide Biodiversity: largest species extinction in 75 million yrs Climate Change: $10 trillion in economic damage
and we can’t continue wasting water ! Fresh water use by industry, Gladstone, Central Queensland
and an old solution isn’t going to help 12/10/20146 Burn Coal Drought Desalination CLIMATE CHANGE OUR RESPONSE
We need to develop new approaches Which put costs against previous ‘externalities’; Which incorporate these costs into business models; To enable us to secure management support and ‘buy-in’; And which drive behavioural, process design and operational changes.
First Step to Resilience is Future Proofing Move the accounting perspective (decision window) out to the future. 12/10/201410 Expanded Decision Window Normal Decision Window Future proofing of projects Now20 Years $8/T $20/T$85/T? Cost of CO 2 emissions $0.1/m 3 $ 1.0/m 3 $5/m 3 ? Cost of Water $0.05/kWhr $ 0.50/kWhr$1/kWhr? Cost of Energy Cost of Waste Disposal Cost of Compliance
Second step – measure and analyse Gladstone Region Water Demand by End Use
Next steps – review all usage Do more with less – evaluate increased solids density in slurries / pastes / filter cake deposition ‘Future proofing’ means putting ‘future’ cost rather than ‘historical’ costs into water pricing models Best Appropriate Practice – value engineering examines the contribution of water in the process – and examines quality of water required. This often encourages use of lowest quality water / seawater for low value uses such as cooling ; Total Quality Management - excess material useage (incl water use) is a variance from TQM - zero defects and zero waste are now key business drivers;
And start to widen the perspective 12/10/201413 Sustainability Impact Reduction Efficiency Conventional project engineering: NPV focus with Strategic Economic Analysis
To enable a Whole Project Cost Benefit Analysis 12/10/201414
Whether you take a social view (Green) 12/10/201415 World is changing −Inexorably rising population −Huge stress on natural world −Massive resource demands −Species extinctions −Changing climate −Significant global risks for humanity To meet challenge: −Build in business resilience −Facility modification −Increase efficiency −Reduce energy consumption −Clean up, reduce emissions −Engage stakeholders
Or a financial view (Black) 12/10/201416 World is changing −Increasing energy costs −Increasing resource costs (water, etc) −Tightening legislation −Public opinion and community attitudes changing −Increased costs of environmental and social compliance −Volatility To meet challenge: −Build in business resilience −Facility modification −Increase efficiency −Reduce energy consumption −Clean up, reduce emissions −Engage stakeholders

EcoNomic Evolution Long pastYesterday EcoNomics
Branding 12/10/201420 Nomics - …from the Greek ‘nomikos’ meaning law Wikipedia … Laws of logic and nature Shorter Oxford English Dictionary ‘Nomic is a game in which changing the rules is a move. - Peter Suber, the creator of Nomic, The Paradox of Self Amendment, App 3 P362 Economics … The science that deals with production, distribution and consumption of goods and services or the material welfare of human kind. The maximization of human welfare. Eco - … from the Greek ‘oikos’ meaning house. Used as a prefix (as in ecology, ecosystems) concerned with living thing in relation to their environment.
EcoNomics is a whole new way to deliver projects Select and design for sustainability from the outset Look outside the facility limits Look over the longer term Explicitly monetise all environmental and social risks, impacts and opportunities Mandate the entire project team to achieve sustainability objectives Train wide range of staff to contribute to sustainability within a project Embed best available technical capabilities within project teams Proprietary tools and systems to support the project 12/10/201421
